Abstract

Bei einer in einem Kraftfahrzeug angeordneten Verbrennungskraftmaschine (1) mit in Reihe angeordneten Zylindern und einem Quereinbau werden die Abgase von der der Fahrtrichtung entgegengesetzten Seite der Verbrennungskraftmaschine in Fahrtrichtung nach vorne um die Verbrennungskraftmaschine herum geführt und gelangen von dort zu einem im mittleren Bereich des Kraftfahrzeuges angeordneten NOx-Falle (8). Zur raschen Aufheizung beim Kaltstart ist der Drei-Wege-Katalysator (12) unmittelbar nach den Abgaskrümmern (2) angeordnet; außerdem werden durch eine kurze Zuleitung (5) bei geschlossenem Ventil (9) die Abgase unmittelbar einer Abgasleitung (13) zugeleitet, die in eine NOx-Falle (8) mündet.
